Geotechnical design and construction considerations for Old Mandurah Traffic Bridge Project
The Old Mandurah Traffic Bridge (OMTB) project comprised the design and construction of a new incrementally launched bridge supported on five piers (six span structure). The new structure was constructed to the north of the existing bridge, with a realignment of Old Coast Road and Pinjarra Road required over a length of about 500 m. This paper presents the foundation design adopted for various components of the OMTB (approach embankments, temporary casting bed, abutments, piers and boardwalk) taking into consideration geotechnical risks, temporary works, and construction constraints which resulted in a holistic design that is efficient and economical. The design is compared with relevant construction records and monitoring test results. Various pile types used for the abutments, piers and boardwalk included 400 mm square reinforced precast concrete piles and 450 mm and 610 mm diameter close ended steel pipe piles with concrete infill. Rigid inclusions were adopted to support the western approach embankment across a zone of very loose sand.
